I own a 2001 ford expedition 4.6 liter vehicle. I am having problems with the heater. The blower works fine but the air is only slightly warmer than the temp outside. I have changed the thermostat, I thought it may be hung open not allowing the coolant to get warm enough, but that did not fix it. Do you think there may be a blockage in the line to the heater core? There are no coolant leaks to be found. Thank you fro your time,
have the same problem?
